EGR 213 Problem Set 5
1. Two vertical forces are applied to a beam of the cross section shown. Determine the maximum tensile and compressive
stresses in portion BC of the beam. (3 points)
Figure 1
2. A 60-N·m couple is applied to the steel bar shown. Assuming that the couple is applied about the z axis as shown,
determine the maximum stress and the radius of curvature of the bar. Use E = 200 GPa. (3 points)
